AISI,DIN,GB,JIS 304 316 201 202 302HQ 304HC stainless steel cold heading wire

Cold heading wire is processed to combine formability and ductility with enduring strength.

This makes it ideal for manufacturing fasteners and fixings such as bolts, screws, pins, rivets, studs and tie rods.

Quality

Toponewire cold heading wire features a blend of charac­te­ristics that are vital in the production of fasteners and fixings. They have excellent corrosion resistance, high formability, a good surface finish and low magnetism after heading and threading.

We incorporate a high level of inspection and quality control to ensure consistency throughout the wire, resulting in a high-quality product with a longer lasting die life and increased machi­nability. We also work within the scope of ISO 9001:2015 management system.

Coatings

To ensure maximum performance and efficiency when machining, our cold heading wire can be supplied with a consistent soap coating that enables the forming machines to run efficiently at high speeds.

Bright surface are available depending on our customers’ specifi­cations.

Grades

Our cold heading wire is available in a variety of 300 and 400 series. Each grade has its own charac­te­ristics.

The most common are, 302HQ, a specialised wire grade, largely used for the manufacture of stainless steel fasteners, includes 3% copper to reduce the cold work hardening rate, it is the standard metal for the manufacture of self-tapping screws and light machine screws.
